Detailed Luggage Guidelines
Here is the full breakdown of size sizer dimensions, weight caps, and carry-on/checked bag policies.
| Luggage Type | Maximum Size (Inches) | Maximum Size (Metric) | Weight Cap | Standard Cost |
|---|---|---|---|---|
| Personal Item | 16 x 13 x 6 in | 41 x 33 x 15 cm | No strict limit | FREE (Fits under seat) |
| Carry-On Bag | 21 x 15 x 9 in | 53 x 38 x 23 cm | No limit (must lift) | Free carry-on except for "UltraBasic" fares |
| 1st Checked Bag | Max 62 linear inches | Max 157 linear cm | Max 50 lbs | $35 USD |
WestJet recently introduced "UltraBasic" fares, which block carry-on bag access. If you purchase an UltraBasic fare, do not try to sneak a carry-on past the gate; they will charge you a $60 gate check fee plus the regular bag fee.
Best bag selection: Choose a compact underseat bag if traveling UltraBasic to avoid any gate check penalties.
Baggage Penalty & Excess Fees
Exceeding either sizer dimensions or weight caps will result in extra charges at check-in or boarding gates.
| Fee Category | Domestic US Rate | Details |
|---|---|---|
| 1st Checked Bag Fee | $35 | $35 - $42 CAD for 1st bag (cheaper online), $50 - $60 CAD for 2nd bag. |
| 2nd Checked Bag Fee | $50 | Standard rate for economy passengers. |
| Overweight Charge | $100 | Applies if the bag exceeds standard weight caps (e.g. 50 lbs / 23 kg). |
| Oversized Charge | $100 | Applies if the bag linear dimensions exceed 62 inches. |
